Mammut DRYtech
DRYtech™ is our windproof and waterproof quality which provides permanent protection from rain, snow, wind and weather. What is more, the high quality and performance of the materials make these products extremely comfortable to wear. DRYtech™'s breathability is the result of the membrane's hydrophilic properties. The membrane absorbs and locks in perspiration (like a sponge). When it becomes full, the moisture is evacuated away from the body.
